Why Cottage ADU Builders Is Perris’s Preferred Bathroom Remodeling Company
Perris homeowners don’t have time for contractors who learn on the job at their expense. Our Bathroom Remodeling team has opened up dozens of bathrooms in the 92570, 92571, and 92572 zip codes, and we know what’s behind those stucco walls before we swing a hammer. Homes off Nuevo Road near the Perris Valley Airport, properties in the May Ranch area, and the older tracts along Rider Street all share the same story: galvanized supply lines that corrode from the inside out, original drain lines that were barely adequate when they were installed, and waterproofing that gave up years ago.
Neil Stratton started this company with a single trade focus: residential square-footage improvements. That means we’re not chasing roofing jobs in Menifee or landscaping work in Moreno Valley. We’re in Perris bathrooms and kitchens, plus the ADUs our brand portfolio supports. When you call us, you get a team that has already solved the exact problems your Perris home likely has. We write line-item change orders, we pull permits, and we pass inspections. That’s not marketing language. That’s how the job gets done.
Our Bathroom Remodeling Services in Perris
Full Bathroom Remodels
A full bathroom remodel in Perris means demolition down to the studs, new plumbing where needed, new electrical, new waterproofing, and a finish that holds up to the 100°F-plus summers we get out here. We start every job with a camera inspection of the drain lines and a visual check of the supply plumbing. If you’re in a 1990s tract home near Evans Road or a 2000s build off Mapes Road, chances are good we’ll recommend replacing the original valves and supply lines while the wall is open. The cost of doing it then versus after we’ve tiled is the difference between a few hundred dollars and a few thousand.

Shower and Tub Replacements
Shower and tub replacements in Perris run $8,000 to $15,000, with the spread driven by what the demolition reveals. In homes around Orange Avenue and the downtown corridor, we regularly find shower pans that have been leaking into the subfloor for years. The tile looks fine from the outside, but the framing underneath is soft and needs rebuilding. We replace the pan, rebuild the framing, and install a waterproofing system like Schluter Kerdi with a proper slope and drain assembly. That’s the only way a shower lasts through Perris’s heat cycles, which expand and contract everything repeatedly.

Vanity and Fixture Upgrades
A vanity and fixture upgrade in Perris can run anywhere from $3,500 for a straightforward swap to $9,000 if you’re moving plumbing lines or adding a double-sink configuration that requires rerouting the drain. The older homes near the Lake Perris State Recreation Area often have single-sink vanities with very little working space, and homeowners want two sinks but don’t realize the original drain line can’t handle the additional flow without modification. We’ll tell you up front what’s achievable with the existing rough-in before you spend money on a vanity that won’t fit.

Trusted Brands We Service in Perris
Cottage ADU Builders works with the brands you’ve already been researching, and that goes for bathroom work too. Our familiarity with the building systems behind Mighty Buildings, Boxabl, and Plant Prefab means we understand factory tolerances, utility sequencing, and how those same principles apply to a bathroom that has to fit perfectly in an existing Perris home. We also specify James Hardie fiber-cement materials on applicable exterior applications, because a bathroom that’s built well inside needs a house that holds up outside. For Perris homeowners, that means we’re not guessing at material compatibility or install requirements. We know what works in this climate and on these lots.
Common Bathroom Remodeling Problems We See in Perris Homes
- Galvanized supply lines with pencil-thin openings. Homes built in the 1980s and 1990s across Perris used galvanized steel for supply plumbing, and after 30 – 40 years of Perris’s hard water, the interior diameter can shrink by 80 percent. That’s why your shower pressure stinks even after you replace the showerhead.
- Original shower pans leaking into the subfloor. The shower pans installed in Perris tract homes from that era were often vinyl liners with no preslope, and they fail silently. By the time you see cracked grout or smell mildew, the framing underneath is already compromised.
- Undersized exhaust ventilation for attic heat. Attic temperatures in Perris hit 140°F in summer. A builder-grade vent fan can’t move enough air to prevent moisture buildup in a bathroom exposed to that kind of heat load, so we size replacement fans for the actual cubic footage and the heat load above the ceiling.
- Permit-triggered electrical upgrades. If your bathroom has a pre-1990s electrical panel or lacks GFCI protection, the City of Perris building inspector will require upgrades the moment we pull a permit for a remodel. General contractors sometimes pretend this won’t happen. We write it into the estimate so it’s not an ambush.

FAQs – Bathroom Remodeling in Perris
The increase comes from hidden conditions that only reveal themselves after demolition: corroded galvanized supply lines, undersized drain plumbing, failed shower pan waterproofing, and permit-triggered electrical upgrades. In Perris’s 1980s – 2000s stucco tract homes, the original plumbing was often marginal from day one, and 30 – 40 years of hard water and summer heat cycles have made it worse. We can’t see behind drywall any better than you can, which is why we write allowances into the contract for the most common issues and require a signed change order with exact pricing before we do anything beyond the original scope. Call (866) 808-7312 for an estimate that includes realistic allowances for your home’s age and plumbing type.
Yes, any bathroom remodel that moves plumbing, changes electrical, or alters framing requires a permit from the City of Perris. The permit will trigger code compliance for anything the inspector sees: GFCI outlets, a dedicated vent fan circuit, and current waterproofing standards. Many Perris homes built before the 2000s don’t have a dedicated circuit for the bathroom exhaust fan, and once the wall is open, the inspector will require it. We handle the permit application, schedule inspections, and price these upgrades into the initial estimate as line items. You’ll know what the city requires before we start, not halfway through.
Perris regularly sees summer highs over 100°F, and attic temperatures in the 140°F range, which means bathroom ventilation has to be sized differently than in coastal California. A standard builder-grade fan can’t keep up with the moisture load in a bathroom that sits under a superheated attic for four months a year. We also specify adhesives, caulks, and waterproofing membranes rated for high-heat environments, because materials that work in Long Beach fail in Perris. Your bathroom has to handle extreme thermal cycling, and we build for that from the rough-in stage through final finish.
Expect to replace it. Galvanized supply lines in Perris homes from the 1980s and 1990s are typically corroded to the point where the interior opening is smaller than a #2 pencil, regardless of how the exterior looks. We repipe the bathroom supply lines with PEX while the walls are open, which typically costs $2,500 to $5,000 depending on the layout and access. It’s not optional work in most cases, because connecting new fixtures to old galvanized lines just creates a failure point behind a finished wall. The time to do it is during the remodel, not after you’ve paid for tile and trim.
Yes, but access constraints affect how we stage materials and dispose of demolition debris. Homes off Rider Street, along Evans Road, and in the older tracts near downtown Perris often have narrow side yards and block walls that limit access to the rear, so we bring materials through the garage or a protected pathway and schedule debris haul-off for the same day we demo. The work itself doesn’t change, but the logistics do, and we plan for them before the first day. We’ve done enough bathrooms in Perris’s standard subdivision lots to know exactly how to work around a 5-foot side yard and a block fence that can’t be moved.
